This Viral Bath Bomb Video Shows How to Make Your Tub Into a Real-Life Horror Show

In the 26-second video, which has thus far received over 1.5 million views since being posted Saturday by Instagram user toxicbitchcraft, a black bath bomb is slowly submerged into a bathtub, creating what looks like a behind-the-scenes Harry Potter featurette.
